TTi TGF4082 Dual Channel Arbitrary Function Generator – 160MHz

The TGF4000 series of function/arbitrary generators offers signal generation capability up to 240MHz on two identical full performance channels that can operate independently or in coupled or tracking modes. Precise channel to channel phase control with a resolution of 0.001° is provided.

A wide range of built-in waveforms is included and custom arbitrary waveforms can be used at sample speeds up to 800MS/s and replay rates up to 80MHz. PC-based arbitrary waveform generation and editing software are provided.

High resolution, low jitter pulses can be generated up to 100MHz as can wide bandwidth white noise. An extensive array of modulations is provided using internal and external sources. Gated, burst, and sweep modes can use internal or external trigger sources.

Remote control via USB and LXI compliant LAN (standard) can be supplemented by optional GPIB if required.

Extensive Features

Exceptional Performance

Higher Frequencies

The TGF4000 Series out-performs other generators in its price range by offering high purity sine waves up to 240MHz and square waves up to 100MHz, with low harmonic distortion and low phase noise, audio band THD is significantly better than similar generators at just 0.05%.

Exceptional Frequency Precision

The frequency of these waveforms can be set with up to 15 digits or one micro hertz of resolution. The DDS based frequency generation system uses a high stability TCXO timebase oscillator.

High Frequency and Resolution Pulse

The pulse generator function offers an exceptionally high pulse width resolution of 100ps over a period range from 10ns to 1000s. The pulse edge speed is independently variable from 3ns to 800s. Pulse jitter is dramatically lower than any comparable generator at only 30ps

PRBS Generator *

PRBS (Pseudo-Random Bit Sequence) is a binary waveform type that is widely used within secure communications systems. PRBS is offered with a choice of 8 sequence lengths at rates between 1mbps and 100Mbps.

PRBS can be used as both a carrier waveform and a modulation.

Harmonics Generator *

The harmonics generator function built into the TGF4000 series enables waveforms to be created by the addition of sine wave harmonics. Up to 16 harmonics can be used, chosen from up to the 50th order. The amplitude and phase can be individually set for each harmonic.

Frequency Counter/Timer

The frequency counter function allows external signals to be measured in terms of frequency, period, pulse width or duty cycle. The frequency range is 0.1Hz to 125MHz with a measurement resolution of up to seven digits. Both generator channels remain operational when the counter is in use.

Extensive Digital & Analog Modulations

A large set of modulation types are built-in including AM, FM, PM, FSK, ASK, BPSK, PWM and SUM. All standard and arbitrary waveforms can be modulated as the carrier, although Noise, Pulse and PRBS are limited to AM, ASK and SUM modulations plus PWM for Pulse.

Internal Digital Modulations

AM, FM, PM, PWM and SUM modulations can use an internal modulation source based upon any standard or arbitrary waveform type or Noise. A very wide modulation frequency range of 1µHz to 10MHz can be used. FSK, ASK, and BPSK use a square wave modulation signal adjustable between 2mHz and 10MHz.

External Analog Modulation and Triggering

All modulation types can use an external modulation signal, either analog (AM, FM, PM, PWM and SUM) or digital triggering (FSK, ASK, and BPSK). The analog modulation input bandwidth is DC to 5MHz.

Sum Modulation

SUM modulation, not offered by most other products, enables the modulation waveform to be added to the carrier at any percentage. All waveform types including Pulse and PRBS can be SUM modulated. This is particularly useful using Noise as the modulator to test circuit resilience with noisy signals.

Wideband Noise Generator

The Noise function provides wideband gaussian noise at bandwidths up to 100MHz and crest factor of more than five. Noise can be used both as a carrier waveform and as a modulating waveform for AM, FM, PM, PWM and SUM modulation types. As a carrier it can be AM, ASK or SUM modulated.

Built-In Waveforms

A large number of standard and pre-built arbitrary waveforms are built into the generator. These include triangles, ramps, sinc, logarithmics, exponentials, gaussians and cardiac (among others). High sampling rate allows higher repetition rates than other generators.

Custom Arbitrary Waveforms

Custom arbitrary waveforms of 16 bit vertical resolution and up to 8192 points can be defined and replayed at sampling rates up to 800MS/s and repetition rates up to 80MHz.

Enhanced Connectivity

  • FULL REMOTE CONTROL All
    • functions of the generators can be controlled from the digital interfaces. Arbitrary waveform data can also be loaded using these interfaces.
  • LAN
    • The LAN interface uses a standard 10/100 base-T Ethernet hardware connection with ICMP and TCP/IP Protocol for connection to a Local Area Network or direct connection to a single PC. This interface supports LXI and is highly appropriate for system use because of its scalable nature and low cost interconnection.
  • LXI
    • The LAN interface is LXI compliant. LXI (LAN eXtensions for Instrumentation) is the next-generation, LAN-based modular architecture standard for automated test systems managed by the LXI Consortium, and is expected to become the successor to GPIB in many systems.
  • GPIB (OPTIONAL)
    • The GPIB interface is compliant with IEEE-488.1 and IEEE-488.2. GPIB remains a widely used interface for system applications.
  • USB
    • USB provides a simple and convenient means of connection to a PC and is particularly appropriate for small system use. A USB driver is provided which supports Windows 2000 and above including Win 8 and 10.
  • LABVIEW & IVI DRIVER
    • An IVI driver for Windows is included. This provides support for common highlevel applications such as LabView*, LabWindows*, and Keysight VEE*.
  • WEB INTERFACE
    • The TGF4000 has a built-in LXI compliant web server which provides information on the unit and allows it to be configured over the LAN, quickly allowing the unit to be controlled via PC or tablet at no extra cost. Simple command line control from the browser is also possible.
  • WAVEFORM SOFTWARE
    • Both generators are supplied with Waveform Manager Plus software for Windows. This PC software enables complex arbitrary waveforms to be created and edited. Waveforms can be built in any number of sections using any combination of standard waveforms, mathematical expressions, drawn waveforms, uploaded waveforms, imported waveforms and existing stored waveforms. Waveforms can be transfered to the generator using either the Flash drive interface or the bus interfaces.
  • FREQUENCY REFERENCE
    • The generators use a high quality TCXO crystal as the internal frequency reference providing 1ppm accuracy and stability. If a higher accuracy or stability is required, an external 10MHz reference signal (from an off-air standard for example) can be applied to the Ref. Clock input. The internal 10MHz clock is available as a rear panel output for synchronisation with external equipment.
  • SYNC OUTPUT
    • Channel 2 can be configured to be a Sync output for channel 1. Sync can be chosen to perform a variety of tasks depending upon the waveform type and the application.
  • MAIN OUTPUTS
    • The main outputs can provide up to 10V pk-pk into 50Ω (20V pkpk EMF) for frequencies up to 80MHz. Maximum amplitude is reduced for higher frequencies. High levels of DC offset can be set in conjunction with low signal levels, and the attenuator can be fixed to prevent glitches when changing levels. Amplitudes can be entered as peak to peak voltage plus offset or in terms of high level and low level The amplitudes are shown relative to a 50Ω load impedance or as the open circuit EMF values. Alternatively the user can enter any load value between 1Ω to 10kΩ and the amplitude will be calculated accordingly.
  • OTHER INPUTS
    • In addition to the Reference Clock input and output sockets, rear panel inputs for Modulation and Trigger are provided. These are used both for the modulation and triggering/gating functions and for the external frequency counter function.

WAVEFORM EDITING

Basic waveform creation and editing is built into the generator. However for complex waveforms Waveform Manager Plus software is included. This Windows based package enables almost any waveform shape to be created using mathematical expressions, freehand drawing, waveform libraries, and import of waveforms using the Clip Board.

WAVEFORM TRANSFER AND STORAGE

Waveforms can be stored on Flash drives using the front panel mounted USB host interface. Waveforms can be transferred from or to a PC either using a Flash drive, or via the digital interfaces (USB, LAN or GPIB).
